As DIG (Naxalites), Sinha showed rare intellectual integrity and courage by writing three articles in the English daily The Searchlight recognising the naxalite movement as a socio-economic and political issue and not just as a mere policing job. In these pioneering articles, Sinha stated, ““putting in zealous and dedicated social reformers drawn from all shades to bring about transformation on the socio-cultural planes’ is as much a part of ‘the counter-insurgency measures’ as ‘concentrated police operations or operations by the special task forces, may be from the supreme armed formation, the army itself.” This has been seen as major critical interpretation of the movements like Bhoodan in India started by Vinoba Bhave.
